Make a 3D Printed Kit with Meshmixer 2.7

[source]

Meshmixer 2.7 was released today full of new tools for 3D printing. Here I use the new version of the app to create a 3D printed kit of parts that can be printed in one job and assembled together pin connectors.

To do this I used several of the new features to make this a fast and painless process. I dug up a 123D Catch capture I took of a bronze sculpture of John Muir. I found it in my dentists office, it turns out my dentist sculpted it. I thought I’d make my own take on it by slicing it up and connecting it back together so it can be interactive, swiveling the pieces around the pin connectors.

I made use of the new pin connectors solid parts that are included in the release (in the miscellaneous bin). I also used the powerful Layout/Packing tool to layout parts on the print bed as a kit of parts to print in one print job. Also, the addition of the Orthographic view is incredibly helpful when creating the kit and laying it out within the print volume of my Replicator 2X. An instructable is in progress with a how-to for a 3D printed kit such as this.

 

This new release has some other nice updates. Check em out below:

– New Layout/Packing Tool under Analysis for 3D print bed layout

– New Deviation Tool for visualizing max distance between two objects (ie original & reduced version)

– New Clearance Tool for visualizing min distance between two objects (ie to verify tolerances)

– Under Analysis menu, requires selection of two objects)

– Reduce Tool now supports reducing to triangle count, (approximate) maximum deviation

– Support Generation improvements

– Better DLP/SLA preset

– Can now draw horizontal bars in support generator

– Ctrl-click now deletes all support segments above click point

– Shift-ctrl-click to only delete clicked segment

– Solid Part dropping now has built-in option to boolean add/subtract

– Can set operation-type preference during Convert To Solid Part

– Can set option to preserve physical dimensions during Convert To Solid Part

– New Snapping options in Measure tool

– Can now turn on Print Bed rendering in Modeling view (under View menu)

– Must enter Print View to change/configure printer

– Improved support for low-end graphics cards

For your kit of parts, try out the new pin connectors included in the Misc. parts library. One is a negative (boolean subtract it when dropping the part). The other you can drop on the print bed for printing by itself. It fits into the negative hole. You can also author your own parts and they will drop at a fixed scale (so they fit!).

Let us know what kind of kits you create…maybe we can add in your connectors in a future release. (There’s a free 3d print and t-shirt involved). Let us know at meshmixer@autodesk.com.

Have fun!!

Leica Geosystems HDS Introduces Patent-Pending Innovations for Laser Scanning Project Efficiency

With Leica Cyclone 9.0, the industry leading point cloud solution for processing laser scan data, Leica Geosystems HDS introduces major, patent-pending innovations for greater project efficiency. Innovations benefit both field and office via significantly faster, easier scan registration, plus quicker deliverable creation thanks to better 2D and 3D drafting tools and steel modelling. Cyclone 9.0 allows users to scale easily for larger, more complex projects while ensuring high quality deliverables consistently.

Greatest advancement in office scan registration since cloud-to-cloud registration
When Leica Geosystems pioneered cloud-to-cloud registration, it enabled users – for the first time – to accurately execute laser scanning projects without having to physically place special targets around the scene, scan them, and model them in the office. With cloud-to-cloud registration software, users take advantage of overlaps among scans to register them together.

“The cloud-to-cloud registration approach has delivered significant logistical benefits onsite and time savings for many projects. We’ve constantly improved it, but the new Automatic Scan Alignment and Visual Registration capabilities in Cyclone 9.0 represent the biggest advancement in cloud-to-cloud registration since we introduced it,” explained Dr. Chris Thewalt, VP Laser Scanning Software. “Cyclone 9.0 lets users benefit from targetless scanning more often by performing the critical scan registration step far more efficiently in the office for many projects. As users increase the size and scope of their scanning projects, Cyclone 9.0 pays even bigger dividends. Any user who registers laser scan data will find great value in these capabilities.“

With the push of a button, Cyclone 9.0 automatically processes scans, and digital images if available, to create groups of overlapping scans that are initially aligned to each other. Once scan alignment is completed, algorithmic registration is applied for final registration. This new workflow option can be used in conjunction with target registration methods as well. These combined capabilities not only make the most challenging registration scenarios feasible, but also exponentially faster. Even novice users will appreciate their ease-of-use and ready scalability beyond small projects.

Power user Marta Wren, technical specialist at Plowman Craven Associates (PCA – leading UK chartered surveying firm) found that Cyclone 9.0’s Visual Registration tools alone sped up registration processing of scans by up to four times (4X) faster than previous methods. PCA uses laser scanning for civil infrastructure, commercial property, forensics, entertainment, and Building Information Modelling (BIM) applications.

New intuitive 2D and 3D drafting from laser scans
For civil applications, new roadway alignment drafting tools let users import LandXML-based roadway alignments or use simple polylines imported or created in Cyclone. These tools allow users to easily create cross section templates using feature codes, as well as copy them to the next station and visually adjust them to fit roadway conditions at the new location. A new vertical exaggeration tool in Cyclone 9.0 allows users to clearly see subtle changes in elevation; linework created between cross sections along the roadway can be used as breaklines for surface meshing or for 2D maps and drawings in other applications.

For 2D drafting of forensic scenes, building and BIM workflows, a new Quick Slice tool streamlines the process of creating a 2D sketch plane for drafting items, such as building footprints and sections, into just one step. A user only needs to pick one or two points on the face of a building to get started. This tool can also be used to quickly analyse the quality of registrations by visually checking where point clouds overlap.

Also included in Cyclone 9.0 are powerful, automatic point extraction features first introduced in Cyclone II TOPO and Leica CloudWorx. These include efficient SmartPicks for automatically finding bottom, top, and tie point locations and Points-on-a-Grid for automatically placing up to a thousand scan survey points on a grid for ground surfaces or building faces.

Simplified steel fitting of laser scan data
For plant, civil, building and BIM applications, Cyclone 9.0 also introduces a patent-pending innovation for modelling steel from point cloud data more quickly and easily. Unlike time consuming methods that require either processing an entire available cloud to fit a steel shape or isolating a cloud section before fitting, this new tool lets users to quickly and accurately model specific steel elements directly within congested point clouds. Users only need to make two picks along a steel member to model it. Shapes include wide flange, channel, angle, tee, and rectangular tube shapes.

Faster path to deliverables
Leica Cyclone 9.0 also provides users with valuable, new capabilities for faster creation of deliverables for civil, architectural, BIM, plant, and forensic scene documentation from laser scans and High-Definition Surveying™ (HDS™).
